Thanks for the tips guys. After thinking about it, I am not 100% positive it worked when new. I do know it went through the alignment without problems, so I better check my wound coils just to be safe. Everything else seems to work OK and the only issue is lack of sensitivity on 20 meters.

The problem is that you need a fair amount of signal to get any indication on the average oscilloscope. The normal method is to use an RF millvoltmeter to trace the path. You can use the Elecraft provided RF probe and a DVM providing you can inject an on frequency signal of sufficient level to work through the RX bandpass filters, etc. Elecraft give a figure of 140mV from the signal generator to carry out this test There is a good description how to go about it in the rev F, K2 manual Appendix E, Troubleshooting page 11. It is possible under extreme circumstances to use a TX into a dummy load as a signal source, but needs extreme care how you would extract sufficient level without smoking the RX front end. Much better to use a suitable signal generator.
